High-precision gear processing has high requirements on the company's technology, design, and equipment. If a company wants to make gears well and become stronger and bigger, it must strictly control the following aspects to continuously improve its ability to respond to the market.

1. Technological innovation and upgrading:

The company needs to continuously improve its independent innovation capabilities, have its own core technology, cultivate high-level R&D and high-skilled personnel, and do a good job in the R&D, processing and manufacturing of high-end products (high-precision gears), so as to make the high-end gear market stronger and bigger.

2. Reasonable design:

High-precision gear machining must be reasonably designed to control noise and contact spots. It is necessary to ensure the thermal deformation of the gear product during the transmission adjustment process and how to ensure the uneven temperature distribution in the tooth width direction and the pressure angle change caused by centrifugal force; ensure the elastic deformation of the gear under the action of the working load; ensure the manufacturing and assembly accuracy of the gear, etc.

3. Efficient equipment:

Now it is generally required that only a clamping accuracy of 0.003 μm can guarantee the high precision of the processed gear.

With the upgrading of domestic gear manufacturing, the requirements for fixtures are getting higher and higher, and new gear fixtures are also being continuously applied in production and manufacturing.

4. Tooth surface requirements:

In order to obtain higher gear tooth surface quality, grinding is usually carried out. Its purpose is to eliminate thermal deformation. Improve gear precision and tooth surface roughness.

High-precision gear tooth surfaces are mostly treated with shot peening technology. The positive effect of residual compressive stress and homogenization can enhance the actual resistance of the gear to bending fatigue.

At present, the precision requirements for gear products in the market are getting higher and higher, and the processing manufacturers need the close cooperation of design, technology, manufacturing, inspection and other departments to make high-precision gears. The key technology of gears is a system engineering involving design, manufacturing, heat treatment, raw materials and other aspects.
